In this Nov. 29, 2018 photo, hot cell operators Dawnette Hunter, left, and Scot White manipulate radioactive material from behind 4-foot-thick leaded glass at the Hot Fuel Examination Facility at the Idaho National Laboratory about 50 miles west of Idaho Falls, Idaho. The U.S. Department of Energy has selected Idaho as the site for a proposed nuclear test reactor that would dramatically reduce the time needed to develop nuclear fuels and components for a new generation of nuclear reactors. The Energy Department on Wednesday, July 27, 2022, said it selected its 890-square-mile site in eastern Idaho that includes the Idaho National Laboratory to build the Versatile Test Reactor, or VTR.

This photo released by Idaho National Laboratory shows its Advanced Test Reactor at Sunrise at Idaho National Laboratory's desert site about 50 miles west of Idaho Falls, Idaho, on Jan. 31, 2007. Scientists in Idaho have completed a rare overhaul of one of the world's most powerful nuclear test reactors. Officials at the Idaho National Laboratory said Monday, April 18, 2022, that normal operations are expected to resume later this spring at the Advanced Test Reactor following low-power system checks to make sure the reactor is in working order.
